[PATCH] [SCSI] Create menu entry for the SCSI_WAIT_SCAN config variable

[Dmitri Vorobiev]

The scsi_wait_scan module lacks a menu entry and help text. The
patch adds those, and also makes the module disabled by default,
so that it is compiled only for those targets, which consciously
need it.

This is silly.  There is no harm in compiling this module.
